deviceControlConnectionDownDTR

Module: MOXA-NP6000-MIB

OID (symbolic): MOXA-NP6000-MIB::deviceControlConnectionDownDTR

OID (numeric): 1.3.6.1.4.1.8691.2.8.1.4.1.2.1.1.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: For some applications, serial devices must obtain the Ethernet link status by reading the DTR signal from the NPort 6000 series device server. If this setting is set to 'goes low,' DTR will change its state to low if the Ethernet link is off.

What is deviceControlConnectionDownDTR?

Controls what the DTR signal on this serial port does when the Ethernet link goes down: goes-low(1) drops DTR so the attached serial device can detect the outage, or always-high(0) leaves DTR unchanged. It mirrors deviceControlConnectionDownRTS but for the DTR line instead of RTS.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> MOXA-NP6000-MIB::deviceControlConnectionDownDTR

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.8691.2.8.1.4.1.2.1.1.1.8.1
snmpget -v2c -c public <target> MOXA-NP6000-MIB::deviceControlConnectionDownDTR.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.8691.2.8.1.4.1.2.1.1.1.8.1 i <value>
